2015-06-10Fix segfault in module_info for deleted modulesRichard Carlsson
Add a check to protect from segfault when erlang:get_module_info/1/2 is called on a deleted module (i.e. with no current code). Also refactor erts_module_info_0/1 to avoid repeated calls to erts_active_code_ix() and remove some obsolete comments. Add test for module_info on deleted modules.

2015-06-09Fix socket option {linger, {true, 0}} to abort TCP connectionsRory Byrne
Up until now, if {linger, {true, 0}} is set on the socket and there is data in the port driver queue, the connection is not aborted until the port queue is empty and close() is called on the underlying file descriptor. This bug allows an idle TCP client to prevent a server from terminating the connection and freeing resources. This patch fixes the problem by discarding the port queue if the socket is closed when {linger, {true, 0}} is set.
2015-06-09Apply 'show_econnreset' socket option to send errors as wellRory Byrne
Up till now all send errors have been translated into a generic {error, closed}. This patch allows {error, econnreset} to be returned on send errors when it is detected that the TCP peer has sent an RST.
2015-06-09Add 'show_econnreset' TCP socket optionRory Byrne
An ECONNRESET is a socket error which tells us that a TCP peer has sent an RST. The RST indicates that they have aborted the connection and that the payload we have received should not be considered complete. Up until now, the implementation of TCP in inet_drv.c has hidden the receipt of the RST from the user, treating it as though it was just a FIN terminating the read side of the socket. There are many cases where user code needs to be able to distinguish between a socket that was closed normally and one that was aborted. Setting the option {show_econnreset, true} enables the user to receive ECONNRESET errors on both active and passive sockets. A connected socket returned from gen_tcp:accept/1 will inherit the show_econnreset setting of the listening socket. By default this option is set to {show_econnreset, false}. Note that this patch only enables the reporting of ECONNRESET when the socket is being read from. It does not report ECONNRESET (or EPIPE) when the user tries to write to a connection when an RST has already been received. Currently the TCP implementation in inet_drv.c hides all such send errors from the user in favour of returning {error, close}. A separate patch will be needed to enable the reporting of such errors.

All flags was not always set when setting multiple aux work flags at once. This scenario is fortunately quite uncommon and only caused further delay in memory deallocations.

2015-05-27Change hipe_bifs:system_crc/1 to hipe_bifs:system_crc/0Magnus Henoch
The macro HIPE_SYSTEM_CRC used to contain a hidden cookie from the VM that generated hipe_literals.hrl. This means that BEAM files containing that macro would be tied to a particular version of the VM. Change hipe_bifs:system_crc such that it doesn't require a hidden cookie to return the desired value.

2015-05-26Add enif_raise_exceptionSteve Vinoski
Add enif_raise_exception function to allow NIFs to raise error exceptions holding any Erlang terms. This does not replace or deprecate the enif_make_badarg function, though, because raising badarg errors is so idiomatic in NIFs. Reimplement enif_make_badarg on top of enif_raise_exception. Add new tests for enif_raise_exception for both normal and dirty NIFs. Add documentation for enif_raise_exception.
2015-05-26Enhance enif_has_pending_exceptionSteve Vinoski
Sverker Eriksson came up with the following idea: to handle a future ability for NIFs to raise more than just badarg exceptions, modify the recently-added enif_has_pending_exception function to take a second argument: a pointer to ERL_NIF_TERM. If this argument is a null pointer, ignore it. Otherwise, if the first argument, an ErlNifEnv*, has an associated exception, set the pointed-to ERL_NIF_TERM of the second argument to the value of the exception term. Add new tests and documentation for this modification.
2015-05-26Fix for enif_schedule_nif and exceptionsSteve Vinoski
Fix a place where part of the implementation of enif_schedule_nif was not using the ErlNifEnv exception_thrown field when it should have been. Also make the result of enif_schedule_nif return false when passed to enif_is_exception, and add an assertion for this to the nif_SUITE.c tests.
